Warning

: Changing the direction of the throttle servo will also 

change its neutral position. Be certain to confirm the throttle 
servo properly closes the engine’s throttle opening when the 
transmitter’s trigger is at neutral. 

Using the Radio System

 

The TQ 2.4GHz Radio System has been adjusted at the factory for 
correct operation with your model. The adjustment should be 
checked before running the model, in case of movement during 
shipping. Follow these steps:
1.   Turn the transmitter switch on. The status 

LED on the transmitter should be solid 
green (not flashing).

2.   Turn on the receiver switch in the model. 

The switch is located on the rear shock 
tower.

3.   Position the model so that its front wheels are off the ground.
4.   Turn the steering wheel on the transmitter back and forth and 

check for rapid operation of the steering servo. Also, check that 
the steering mechanism is not loose or binding. If the steering 
operates slowly, check for weak receiver batteries.

5.  When looking down at the model, the front wheels should be 

pointing straight ahead. If the wheels are turned slightly to 
the left or right, slowly adjust the steering trim control on the 
transmitter until they are pointing straight ahead.

6.   Operate the throttle trigger on the transmitter and check for 

rapid operation of the throttle servo. When the throttle trigger 
is pulled back, the carburetor should open. When the throttle 
trigger is pushed all the way forward, the brake should lock.

7.   Once adjustments are made, turn off the receiver on your 

model, followed by the hand-held transmitter.

Range-Testing the Radio System

Before each running session with your model, you should range-
test your radio system to ensure that it operates properly.
1.  Turn on the radio system and check its operation as described in 

the previous section.

2.  Have a friend hold the model with the engine off.
3.  Walk away from the model with the transmitter until you reach 

the farthest distance you plan to operate the model.

4.  Operate the controls on the transmitter once again to be sure 

that the model responds correctly.

5.  Do not attempt to operate the model if there is any problem 

with the radio system or any external interference with your 
radio signal at your location.

Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the 
limit of radio range. At 50mph, a model can cover 73 feet every 
second! It’s a thrill, but use caution to keep your model in range. 
If you want to see your model achieve its maximum speed, it is 
best to position yourself in the middle of its running area, not the 
far end, so you drive the model toward and past your position. In 
addition to maximizing the radio’s range, this technique will keep 
your model closer to you, making it easier to see and control.

No matter how fast or far you drive your model, always leave 
adequate space between you, the model, and others. Never 
drive directly toward yourself or others. 

TQ 2.4GHz Binding Instructions

For proper operation, the transmitter and receiver must be 
electronically ‘bound.’

 This has been done for you at the factory. 

Should you ever need to re-bind the system or bind to an 
additional transmitter or receiver, follow these instructions. Note: 
the receiver must be connected to a 4.8-6.0v (nominal) power 
source for binding and the transmitter and receiver must be within 
5 feet of each other.

1. Press and hold the SET button on the transmitter.
2. Turn on the transmitter and release the SET button. The status 

LED will flash red slowly, indicating that the transmitter is in bind 
mode. 

3. Press and hold the LINK button on the receiver. 
4. Turn on the vehicle and release the LINK button. The LED on the 

receiver will flash red, indicating that the receiver is in bind mode.

5. When the LEDs on both the transmitter and the receiver turn solid 

green, the system is bound and ready for use. Confirm that the 
steering and throttle operate properly before driving your model.

maximum range, hold the antenna upright and pointed in 
the direction of the model. Pointing the transmitter away 
from the model will reduce radio range.
